Q: How do I try a free CXC Biology question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CXC CSEC Biology bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CXC Biology students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Biology questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Biology syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A Guyanese farmer wants to ensure that all new sugarcane plants have exactly the same sweetness and disease resistance as the parent plant. Which method of reproduction should the farmer use?

Accepted Answer

Planting stem cuttings from the parent plant — Award 1 mark for B. Planting stem cuttings is vegetative propagation (asexual reproduction) that produces genetically identical plants with the same characteristics. A is incorrect — cross-pollination is sexual reproduction producing variation. C is incorrect — seed formation involves sexual reproduction and produces variation. D is incorrect — selective breeding introduces variation, not identical offspring.

Answer

Introducing genetic variation through selective breeding

Answer

Planting stem cuttings from the parent plant

Answer

Allowing natural seed formation

Answer

Cross-pollination between two parent plants
